Origen

The word pace comes via Old French pas from Latin passus ‘stretch (of the leg)’. As well as stepping, it also meant ‘journey, route’ in early examples. To be put through your paces arose in the mid 18th century from horse-riding. The notion of ‘tempo’ as in change of pace is from the 1950s while pace yourself is only found from the 1970s. Other words from the same root are pass in the sense to go by, passage (Middle English); passenger (Middle English) the ‘n’ added to conform with words like ‘messenger’; and expand, literally to stretch out. The Old French form of expand, espandre, has the special sense of ‘to shed, spill, pour out’ and is the origin of to spawn (Late Middle English).

expansibility

Consequently, the thermal expansibility of the unfolded state of 23-kDa protein is larger than that of the folded state by ~ 1.8 ml/deg mol.

The decrease in thermal expansibility of the transition state relative to the unfolded state leads to a similar conclusion-namely, that the significant structural constraints also existed in the rate-limiting step for the folding.

Banks expanded their issues, and writers began praising the flexibility, expansibility, and wealth-creating power of an irredeemable paper currency.
